LP on Blast via Sushi (v3)

  1. Visit the Sushi Pool UI

Connect the wallet and change the network settings to Blast if you haven’t already done so.

  1. Select Network
  1. Select a Pool

Choose a liquidity pool you're interested in LP. In this example, we will choose USDB/ETH.

  1. Create a position

Click "Create a position" to start LPing.

  1. Select Price Range

Determine the price range within which you're willing to provide liquidity. This step is crucial for concentrated liquidity pools. There are 2 ways to do it:

a. You can set the minimum and maximum price by adjusting the price range bar or ;

b. Entering specific values into the designated boxes. 

Remember that a narrower price range can result in higher fee collection but also increase the risk of being out of range and not earning any fees. Opting for the full range is equivalent to the classic v2, with no concentrated liquidity.

  1. Provide Liquidity Amount

Enter the amount for one token in the pair. The protocol will populate the other token. If one token exceeds the amount, try inputting the other one first. Then Click on “Preview”

  1. Approve tokens

Just like swap, you need to approve the spending cap for the tokens. Click “Approve (TKN)” and approve the tokens individually on your wallet. 

  1. Review & Confirm

Follow the instructions on the UI. Click “Preview”, then “Add Liquidity”. Confirm the transaction in your wallet.

  1. Manage Position

After adding liquidity, you can manage your position by selecting “My position” under the Pools UI. This allows you to adjust or remove your liquidity as needed.
